Abstract
The functional condition of an induction crucible furnace is checked by first establishing a set-point parameter corresponding to an optimum functional condition of the induction crucible furnace and characterizing the vibratory behavior of same. Then, during normal operation of the furnace, an actual-value parameter of the vibratory behavior is determined. These two parameters are then compared and, if a magnitude of a difference therebetween exceeds a threshold, an alarm is generated.
Claims12
A method of checking the functional condition of an induction crucible furnace, the method comprising the following steps:
- establishing a set-point parameter corresponding to an optimum functional condition of the induction crucible furnace in a new condition of the induction crucible furnace under nominal conditions with regard to maintenance and operation and characterizing vibratory behavior thereof;
- determining an actual-value vibratory-behavior parameter in operation of the induction crucible furnace;
- and
- comparing the parameters, determining any difference therebetween, and deriving the functional condition of the furnace from a magnitude of the difference to draw conclusions with respect to a wear condition of the furnace.
